dc.description.abstract | We develop an alternative approach to study the effect of the generic perturbation (in addition to explicitly considering the
loss term) in the nonlinear Klein–Gordon equations. By a change of the variables that cancel the dissipation term we are able
to write the Lagrangian density and then, calculate the Lagrangian as a function of collective variables. We use the Lagrangian
formalism together with the Rice Ansatz to derive the equations of motion of the collective coordinates (CCs) for the perturbed
sine-Gordon (sG) and φ4 systems. For the N collective coordinates, regardless of the Ansatz used, we show that, for the nonlinear
Klein–Gordon equations, this approach is equivalent to the Generalized Traveling Wave Ansatz (GTWA). | es |
